1. Functions
(1) Checking of condition of sensors listed below
¡ Runs checks on the drum master attachment/detachment position
sensor, light reception by the paper ejection jam sensor, drum stop
/ paper ejection jam sensing position sensor, and press roller sensor
¡ Runs checks on encoders, elevator top limit sensor, A/C mode
sensor and B mode sensor
paper sensor
(1) Checking the condition of the listed sensors
q
Access HELP mode H-06, and press the PRINT key.
For the basic procedure for accessing HELP modes.
w
Release the PRINT key. A display indicating the conditions of
the following sensors will appear.
(The BOOK SHADOW ERASE key must be off for this display
to be possible.)
◆ Drum master attachment/detachment position sensor
◆ Light reception by the paper ejection jam sensor
◆ Drum stop / paper ejection jam sensing position sensor
◆ Press roller sensor
e
Press the PRINT key once more. For as long as the key is held
down, a display indicating the conditions of the following sensors
will appear.
◆ Encoder checks
◆ Elevator top limit sensor
◆ A/C mode sensor
◆ B mode sensor
r
Press the STOP key. The HELP mode selection display will
reappear.
a To exit the HELP mode : Turn the power switch OFF.
a To access another HELP mode : Enter the desired mode number
using the numeric keys.
